四维空间中可穿越的虫洞

Traversable wormholes in four dimensions

Juan Maldacena, Alexey Milekhin, Fedor Popov

摘要:

我们提出了一个四维虫洞的解决方案。它是爱因斯坦麦克斯韦理论加上带电无质量费米子的解。费米子产生负的类卡西米尔能量,这使得虫洞成为可能。这是一个长虫洞,不会导致周围空间的因果关系违反。它可以被看作是一对纠缠的近极值黑洞,其相互作用项由费米子场的交换产生。该解决方案可以嵌入在标准模型,使其整体尺寸相比,电弱规模小。

英文摘要:

We present a wormhole solution in four dimensions. It is a solution of an Einstein Maxwell theory plus charged massless fermions. The fermions give rise to a negative Casimir-like energy, which makes the wormhole possible. It is a long wormhole that does not lead to causality violations in the ambient space. It can be viewed as a pair of entangled near extremal black holes with an interaction term generated by the exchange of fermion fields. The solution can be embedded in the Standard Model by making its overall size small compared to the electroweak scale.
